Best ResponseYou've already chosen the best response.2ok you need to find x in terms of f(x) let f(x) = y y = sqrt(3x + 2) square borh sides y^2 = 3x + 2 can you continue?

Best ResponseYou've already chosen the best response.2f1(x) means the inverse of f(x) find x in terms of y: 3x = y^2  2 x = (y^2  2) / 3 now replace x by f1(x) and y by x f1(x) = (x^2  2) / 3
